Law of Conservation of Mass

This is the scientific principle that matter is neither created or destroyed during a chemical change. Basically, what you start with, you have to end with. That is why atoms have to be equal on both sides of the equation.​

Multiple Choice

Carbon dioxide is created by

• Burning fossil fuels

• Cellular respiration

• Decomposing organic matter

• All answers are correct

Multiple Choice

The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed

• Energy cannot be created or destroyed, it can only transformed

• Energy can't be created, destroyed or transformed

• Energy cannot be created or destroyed.

Multiple Choice
